    <description>&lt;P&gt;Hi,&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;I know this subject has already been discussed several times on this forum, but the last thread was an year ago, so I will give it a shot.&lt;/P&gt;
&lt;P&gt;I currently have a map containing 2 layers:&lt;/P&gt;
&lt;UL&gt;
&lt;LI&gt;Companies&lt;/LI&gt;
&lt;LI&gt;Contacts&lt;/LI&gt;
&lt;/UL&gt;
&lt;P&gt;These two entites are linked to each other (1 &lt;STRONG&gt;Contact&lt;/STRONG&gt; always has 1 &lt;STRONG&gt;Company&lt;/STRONG&gt; and 1 &lt;STRONG&gt;Company&lt;/STRONG&gt; can have 0..n &lt;STRONG&gt;Contacts&lt;/STRONG&gt;).&lt;/P&gt;
&lt;P&gt;When selecting in my map (Using the lasso), I would like to have the list of all the Companies &amp;amp; Contacts in a specific area. The result should be the following :&lt;/P&gt;
&lt;P&gt;&amp;nbsp; &amp;nbsp;All &lt;STRONG&gt;Contacts&lt;/STRONG&gt; (in the selected area) &amp;amp; All their related &lt;STRONG&gt;Companies&lt;/STRONG&gt; (No matter where they are located) &lt;BR /&gt;+ All &lt;STRONG&gt;Companies&lt;/STRONG&gt; (in the selected area) &amp;amp; All their related &lt;STRONG&gt;Contacts&lt;/STRONG&gt; (No matter where they are located).&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;I read that it was not possible to select multiple layers at once. Therefore, I was thinking about creating a new column, being the aggregation of both &lt;STRONG&gt;Companies&lt;/STRONG&gt; &amp;amp; &lt;STRONG&gt;Contacts&lt;/STRONG&gt;, but this would probably mess the Qlik associativity up.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Does any one have an idea of how I could handle this?&lt;/P&gt;
&lt;P&gt;Thanks in advance.&lt;/P&gt;</description>
